I have the full BB white-tie getup (GF tailcoat & trouser, pique a/k/a marcella waistcoat, GF detachable collar shirt, marcella bow-tie, silk hose and Peal & Co. patent balmorals). The shirt has, from the top, a collar stud hole, then 3 formal stud holes down the bib, then the flap (with two buttonholes so that men of different heights can choose the appropriate hole into which the trouser button is inserted), then a regular horizontal buttonhole.
The waistcoat features an elastic loop at the bottom. Thus the shirt flap can be threaded through the waistcoat loop and affixed to the trouser, or the waistcoat loop and the shirt buttonhole can both affix to the trouser button. Remember that the GF tailcoat trouser is pleated with a long rise and is thus meant to be worn rather high in order to meet the waistcoat. Trust me it all comes together wonderfully, not anything like the black-cummerbund, black stud-set, black tie, turndown collar pleated front abomination on the BB website
. That should cost someone's job - it's obvious they did the black-tie photo shoot and then just gave the model the tailcoat jacket to throw on.
My one frustration with white tie is that I've never been able to successfully tie one of those thick marcella bow ties and thus had to fall back to the BB pre-tied variety.
